Although store-bought jello (or jelly in British English) is pretty far from paleo (with food coloring and artificial flavors), the main ingredient in jello, gelatin, is actually a naturally occurring animal product. I had always known that jello came from gelatin and that gelatin came somehow from cows, but it hadn’t really occurred to me that jello, even home-made jello, could be healthy! Maybe I just equated it with too much added sugar!
